I just got around to testing it yesterday. It tastes fantastic! Better than the one I brewed last year to give out as Xmas presents. No off flavors present at all.
Carb'd it up in a keg and now the hard part -- waiting to bottle around Xmas time. 'Course it's 100 degrees right now, so at the end of the day I'm not really clambering for a heavy Imperial Stout anyway. Hope my self-control lasts through the Fall though.
